One playlist per add-playlist CLI call made adding a second playlist a chore.
Now YT_PLAYLIST_URLS takes a comma-separated list of playlist URLs (list=
param extracted) or bare ids; the transcripts service seeds the playlists
table from it at boot (insert-if-missing — hand-set labels are never
clobbered), and `python -m youtube_claims.run sync-playlists` does the same
on demand. Documented in both compose files; 3 tests.
Also: queue the two executor-surfaced defects (OrderFilledEvent side,
/api/attribution env hardcode) + the flaky nightly regime build-features
step in the plans index; regime_features 07-16 backfilled supervised.
